Study Notes
General Irrigation Terminologies
- The term "shall" denotes mandatory compliance, while "should" suggests a recommended option among several choices.
Scope of the Standard
- Defines terminology relevant to the classification, planning, design, construction, and operation of irrigation systems.
Key Terminology
- Access Areas: Publicly accessible zones like parks and playgrounds.
- Active Storage: Water volume between minimum and normal levels in a reservoir.
- Actual Crop Evapotranspiration: Evapotranspiration rate affected by soil water availability and other factors, generally less than predicted rates.
- Algal Bloom: Excessive algae growth producing toxins in water bodies.
- Application Efficiency: Ratio of water effectively stored in the root zone to total water applied.
- Aquifer: Geological formation capable of storing and transmitting water.
- Basin Irrigation: Surface irrigation method where water is applied to a level field enclosed by dikes until it infiltrates the soil.
- Border Irrigation: Involves the use of border strips for irrigation allowing water to flow uniformly down a slope.
Hydraulic Terms
- Contamination: Unnatural substance introduction that affects water quality.
- Conveyance Efficiency: Ratio of water received at field inlets to that released at project headworks.
- Critical Depth: Minimum energy content depth in water flow.
- Crop Coefficient: Ratio of actual to potential crop evapotranspiration.
- Effective Rainfall: Rainwater directly usable by crops, excluding runoff or percolation losses.
Irrigation Methods
- Drip Irrigation: Delivers water slowly at low rates directly onto the soil near the plants.
- Sprinkler Irrigation: Mimics rainfall by pumping water through pipes and spraying it into the air.
Storage and Capacity
- Dead Storage: Volume below the intake structure that accounts for sediment accumulation.
- Normal Storage Elevation: Max water elevation achievable without spillway flow.
- Storage Ratio: Indicates cost efficiency of different reservoir types.
Water Quality and Pollution
- Effluent: Wastewater discharges, including industrial and domestic sources.
- Pollutant: Any harmful substance that alters water or land quality.
Miscellaneous Terms
- Seepage: Water loss from transport channels due to percolation or leakage.
- Water Balance: Inflow and outflow tracking for effective irrigation management.
- Watershed: The area draining into a reservoir.
Regulatory Aspects
- Water Right: Legal grant from the government to use water resources.
- Well Log: Documentation of aquifer characteristics, including depth and material composition.
Structural Considerations
- Zoned Embankment: A dam designed with an impervious core and surrounding zones of permeable materials.
